[REQ] rev934 bRC8u01 [MP] Initial MP screen

[batesmotel]

The default tab for the multi-player screen should be the current games tab. (If no current games, then maybe it should be open challenges screen). Having the current games tab initially selected is consistent with the FoG(RB) version and is also where I normally want to go first when logging in to multi-player mode. It's annoying to have to wait for the challenges list to populate if it's long and then have to click again to go to the current games tab.
